This mysterious aircraft never existed in fact, but was still described in the Allied instructions
almost one year after the outbreak of war on Pacific.
It had also another strange Aichi system designation : Aichi AI-104
and was even given code name : Ione.
It is considered that the misunderstaning is closely connected with Italian Cant Z.506 B,
of which photos and descriptions were published in a few Japanese aviation magazines in late 1938.
In similar misunderstanding in the beginning of war the Kawanishi E8K1 was named Adam
and designated Nakajima SKT-97 by the Allied ;D
